7 Application filed anuary 8, 1915. Serial No. 1,176.

To all whom it may concern Be it known that I, LEWELLYN ELKIN, a citizen of the United States, residing at Clarksville, in the county of Montgomery and State of Tennessee, have invented a new and useful Fireplace, of which the following is a specification.

The device forming the subject matter of this application is a fire-place and the invention aims primarily to provide a means whereby air which is heated by the rear or inner wall of the fireplace casing may be delivered back into the room into which the to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing :Figure 1 shows the invention in front elevation; Fig. 2 is a vertical longitudinal section; Fig. 3 is a horizontal transverse section.

In carrying out the present invention there is provided a chimney 1 constituting a part of a wall 2 separating the interior of a building into a room 3 and a room 4. The chimney 1 is provided with a flue-5, the lower end of which defines a soot box 6, the flue 5 being provided with a lateral inlet branch 7 The chimney 1 constitutes a part of the wall 2 and the wall 2 therefore may be described as having a compartment which is denoted by the numeral 8, the compartment 8 being spaced vertically from the lower end of the flue 5. In the wall 2 there is formed a hot air out et opening 9 establishing communication between the room 4 and the upper end of the compartment 8, the outlet 9 being controlled by means of a movable damper 10 of any desired form.

Located within the compartment 8 and spaced from the sides and top of the compartment is a fire-place casing 11 which may be of any desired form. As shown, the casing 11 comprises a downwardly and forwardly inclined back plate 12, a downwardly and rearwardly inclined top 14, and side walls 15, the latter provided with forwardly prolonged extensions 16 which proect beyond the forward face 30 of the chimney 1. The upper edges of the extensions 16 are downwardly and forwardly inclined and support a downwardly and forwardly inclined deflector 17 which may be provided with a thimble 18, the deflector 17 if desired forming a part of a face plate 19 which bridges the space between the casing 11 and the sides and top of the compartment 8, the face plate 19 cooperating with the casing 11 to form a closure for the front side of the compartment.

In the face plate 19 and relatively near to the lower edge thereof cold air inlet openings 20 are formed, the same being controlled by movable dampers 21. Adjacent its upper edge, the face plate 19 is provided with hot air outlet openings 22 controlled by movable dampers 23, the openings 22 being adapted to discharge into the room 3.

If desired, a conical hood 24: of oblong form may be carried by the thimble 18, the hood 24: terminating in a reduced neck 25 communicating with a pipe 26 entering the inlet branch 7 of the flue 5. Projecting-outwardly from the chimney 1 is a shelf 27 which if desired may be equipped with a notch 28 receiving the pipe 26 and the neck 25 adjacent their place of union, thereby to act as a brace for those elements.

Located within the casing 11 is a heating means which may be a grate 29 although, obviously, any suitable heating means may be employed.

In practical operation, presupposing that a grate basket 29 constitutes the heating means, the fuel consumed in the grate basket will heat the air within the casing 11 and the heated air is deflected outwardly into the room 3 as usual, the products of combustion passing away by means of the hood 2 1, the neck 25, the pipe 26 and the flue 5. The location and position f the deflector .17 pr vents the smoke from entering the room 3. Vhen the casing 11 is heated, the air Within the compartment 8 will be heated also. Cold air is admitted through one or both of the openings 20 by a proper manipulation f the dampers 21. The cold air thus entering the compartment 8 is heated by the casing 11, the heated air passing outwardly through one or both of the hot air outlet openings 22 when the dampers 23 are opened, wholly or partially. It will thus be seen that the air heated by the casing 11 in the compartment passes back into the room 3 and aids in heating the room 3. If desired, the outlet 9 may be opened by a proper manipulation of the damper 10, the outlets 22 being closed by the dampers 23. Then, the hot air within the compartment 8 Will pass through the opening 9 into the room 4. It is clear that if the dampers 23 and 10 be opened together, then the heated air rising in the casing 8 will pass into the rooms 3 and 4t.

'lVhen cold air is admitted through openings 20, this air is heated by the back plate 12, and rises. As the air rises, it is directed toward the rear Wall 2, because the back plate 12 slants rearwardly as it extends upwardly, and because the rear edge of the top 14f projects beyond the back plate, as clearly shown in Fig. 2 Owing to the cooperation of the parts above described, the rear wall 2 is adequately heated. It frequently happens that there is a back draft through the opening 9. When there is a back draft through the opening 9, the air thus received Within the compartment 8 is received by the inclined top 14: and is heated thereby, the air thus heated being discharged through the hot air outlets 22, it being noted that the upper edge of the top 14 is located in the same horizontal plane with the hot air outlets. Generally considered, the present invention is so constructed that a proper heating and discharge of the air in case of a back draft will be brought about, and is so constructed that the rear Wall 2 Will be adequately heated.

Having thus described the invention, What is claimed is y In a device of the class described, a chimney having a rear wall defining a compartment, the rear Wall being provided with an opening adjacent its top, the chimney having a fiue separate from the compartment; a face plate constituting a closure for the front of the compartment; a cold air inlet in the face plate adjacent the lower end thereof; a hot air outlet in the face plate adjacent the upper end thereof; a casing assembled with the face plate and projecting into the compartment; a pipe exterior to the chimney and leading from the casing to the flue; and a heating means in the casing; the casing comprising a back plate which is inclined toward the rear wall as it extends upwardly, whereby air admitted through the cold air inlet and heated by the back plate will be directed toward the rear Wall to warm the same; the casing comprising a downwardly and rearwardly inclined top the forward edge of which is located in the same horizontal plane with the hot air outlet, thereby to direct air to the outlet when there is a back draft through the opening, the rear edge of the top projecting beyond the back plate, thereby to direct toward the rear wall heated air arising along the back plate.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signa ture in the presence of tWo Witnesses.
